Digit hair tourniquets are relatively uncommon. There are reports in the literature of hair tourniquets involving other appendages, such as the penis and uvula, however the phenomenon is not widely recognised and is often overlooked by healthcare professionals. This article discusses two case studies in which hair was responsible for creating a tourniquet around a digit. The article explores possible causes and management options for patients, with reference to the case studies. Midwives and health visitors are central to minimising the risk of injury to children as they can educate expectant mothers about this potential problem...

The challenging nature of change is well documented and adequate preparation before implementing a change initiative is critical to reducing resistance and increasing its chances of success. This article describes a service review conducted in preparation for possible change and improvement at an internationally ranked school of nursing and midwifery in an Irish tertiary education institution. The purpose of the review was to examine organisational structures and work activities, including pressures facing the administrative team that supports the school, and to establish whether operations were fit for purpose and capable of continuing to support the international ranking...

Alternative energy sources have received increasing attention in recent years. The possibility of adding value to agricultural wastes, by producing biofuels and other products with economic value from lignocellulosic biomass by enzymatic hydrolysis, has been widely explored. Lignocellulosic biomass, as well as being an abundant residue, is a complex recalcitrant structure that requires a consortium of enzymes for its complete degradation. Pools of enzymes with different specificities acting together usually produce an increase in hydrolysis yield...

Vascular dementia (VaD) generally refers to memory deficits and cognitive abnormalities that are resulted from vascular disease. In this study, we aimed to systematically review the literature wherein therapeutic effects of medicinal plants have been studied on VaD. A systematic literature search was performed in the PubMed, Scopus, Web of Science, Google Scholar, and other databases using VaD, and medicinal plants as key terms. No strict inclusion criteria were defined, and almost all clinical studies were included...

Phase angle (PA) is a ratio between the reactance and resistance obtained by bioelectric impedance analysis and has been interpreted as a cell membrane integrity indicator and a predictor of total body cell mass. A low PA may suggest deterioration of the cell membrane, which in advanced cancer patients may result in a reduced overall survival (OS). This systematic review sought to investigate the current evidence regarding whether there is an association between PA and OS in patients with advanced cancer (ie, metastatic disease)...

BACKGROUND: Hypertrophic cardiomyopathy (HCM) with or without left ventricular apical aneurysm (LVA) had been studied in the past. Midventricular obstruction associated with HCM and LVA is a unique entity that has not been distinguished previously as a separate phenotypic disease in HCM patients. METHODS: A systematic review of Pubmed and Google Scholar was conducted from inception until September 2017 for all observational studies conducted on HCM with midventricular obstruction and LVA...

Chronic viral infections including those by hepatitis B (CHB) virus and hepatitis C (CHC) virus have been reported to be comorbidities of chronic spontaneous urticaria (CSU). Here, we performed the first comprehensive review of the peer-reviewed literature (Pubmed, Web of Science and Google Scholar) on the prevalence of CHB and CHC in patients with CSU and vice versa. The prevalence of CHB and CHC in CSU does not appear to be increased. Less than 5% and less than 2% of CSU patients have markers of CHB and CHC, respectively, according to most of the 32 studies reviewed...

Despite the pervasive use of social media by young adults, there is comparatively little known about whether, and how, engagement in social media influences this group's drinking patterns and risk of alcohol-related problems. We examined the relations between young adults' alcohol-related social media engagement (defined as the posting, liking, commenting, and viewing of alcohol-related social media content) and their drinking behavior and problems. We conducted a systematic review and meta-analysis of studies evaluating the association of alcohol consumption and alcohol-related problems with alcohol-related social media engagement...

BACKGROUND: An intraocular lens (IOL) is a synthetic lens that is surgically implanted within the eye following removal of the crystalline lens, during cataract surgery. While all modern IOLs attenuate the transmission of ultra-violet (UV) light, some IOLs, called blue-blocking or blue-light filtering IOLs, also reduce short-wavelength visible light transmission. The rationale for blue-light filtering IOLs derives primarily from cell culture and animal studies, which suggest that short-wavelength visible light can induce retinal photoxicity...

This review of the scientific literature was designed to consider the prospects for the application of kinesiotaping for the rehabilitation of the post-stroke patients. The relevance of the work arises from the absence of a systemic analysis of the large number of investigations that have been carried out during the past two years. The objective of the present review article was to evaluate the influence of kinesiotaping on the health status of the post-stroke patients and the course of their rehabilitative treatment based on the results of analysis of the scientific reports published during the period from 2015 to 2017...

The cardiovascular diseases occupy a leading place in the structure of overall morbidity affecting the population not only of Russia but also of the majority of the developed countries throughout the world; they thus impose the heavy social and economic burden on both the public healthcare services and the modern society in general. At the same time, systemic atherosclerosis is considered to be one of the most common, severe, and life-threatening condition. Despite the presence of a large number of pharmaceutical and surgical methods for the treatment of this pathology, they are not infrequently lacking the desired effectiveness...

Melatonin (MEL) is a hormone that is produced in the brain and is known to bind to MEL-specific receptors on neuronal membranes in several brain regions. MEL's documented neuroprotective properties, low toxicity, and ability to cross the blood-brain-barrier have led to its evaluation for patients with traumatic brain injury (TBI), a condition for which there are currently no Food and Drug Administration (FDA)-approved therapies. The purpose of this manuscript is to summarize the evidence surrounding the use of melatonin after TBI, as well as identify existing gaps and future directions...

Van De Walle, GP and Vukovich, MD. The effect of nitrate supplementation on exercise tolerance and performance: a systematic review and meta-analysis. J Strength Cond Res 32(6): 1796-1808, 2018-The purpose of this article was to systematically review the current literature and evaluate the overall efficacy of nitrate supplementation on exercise tolerance and performance by meta-analysis. Studies were eligible for inclusion if they met the following criteria: (a) were an experimental trial published in an English peer-reviewed journal; (b) compared the effects of inorganic nitrate consumption with a non-bioactive supplement control or placebo; (c) used a quantifiable measure of exercise performance; and (d) was carried out in apparently healthy participants without disease...

The article is based on the case analysis of a sudden and unexpected intraoperative death of a 51-year-old female patient with hypertrophic cardiomyopathy, who was undergoing a non-cardiac operation in a non-cardiosurgery clinic, from acute precipitation of left ventricular outflow tract obstruction provoked by surgery and anesthesia. It emphasizes the importance of raising non-cardiac anesthesiologists' awareness of the issue and having clear standards of pre-operative evaluation and perioperative management of patients with hypertrophic cardiomyopathy in order to avoid fatal medical errors...

Brain microbleeds are defined as small, circular hypointense changes in T2-sequensec of brain MRI, well demarcated from the surrounding tissue. They represent the phagocytized products of blood distribution extravasated from pathologically altered vessels. The echo-T2-dependent gradient (GRE) and magnetic susceptibility testing (SWI) sequences are usually used to visualize them. The pathogenesis of microbleeds very complex but angiopathy associated with arterial hypertension and cerebral amyloid angiopathy play a special role...

Over the past few decades, a variety of different reagents for stem cell maintenance and differentiation have been commercialized. These reagents share a common goal in facilitating the manufacture of products suitable for cell therapy while reducing the amount of non-defined components. Lessons from developmental biology have identified signalling molecules that can guide the differentiation process in vitro , but less attention has been paid to the extracellular matrix used. With the introduction of more biologically relevant and defined matrices, that better mimic specific cell niches, researchers now have powerful resources to fine-tune their in vitro differentiation systems, which may allow the manufacture of therapeutically relevant cell types...

Liver transplantation represents the standard treatment for people with an end-stage liver disease and some liver-based metabolic disorders; however, shortage of liver donor tissues limits its availability. Furthermore, whole liver replacement eliminates the possibility of using native liver as a possible target for future gene therapy in case of liver-based metabolic defects. Cell therapy has emerged as a potential alternative, as cells can provide the hepatic functions and engraft in the liver parenchyma...
